Coverage under prefix ZSK

Medicare Advantage

This prefix includes Medicare Advantage coverage. MA plans follow CMS guidelines for timely filing (365 days from date of service), which may differ from the commercial plan's deadline. The payer ID for Medicare Advantage claims may differ from the standard commercial payer ID. Verify before submitting.

Traditional Indemnity

Traditional indemnity coverage under this prefix is a fee-for-service plan. Members can see any provider without network restrictions or referral requirements. The plan reimburses a set percentage of usual and customary charges. Claims are submitted directly to the payer listed above.

POS

This prefix is linked to a POS plan. Point of Service coverage gives members a choice at the time of service: use the HMO-style in-network benefit with a referral for lower costs, or access out-of-network providers at reduced coverage levels. The billing approach depends on which option the member chooses.
